I TAKE-UP MECHANISM F A LOOM.

' To all whom't't may concern:

' 'Be it known that We, LAWRENCE B.

JENoKEs and EPPA H. Bron, both citizens of the United States, residingatXVorcester, 1n the county of Worcester and State of Massachusetts,'havejointly. inventedc'ertain new and useful Improvements in a Take- UpMechanism of a Loom,' of which, the following is a specification.

' Our invention relates to a take-up mech.

' anism of a loom, and the object of our invention is to improve uponthe take-up mech anism as ordinarily made, and more particularly toprovide, improved means for disconnecting the gear of the cloth-rollfrom either one of the other gears of the take-up mechanism, and'also toprovide an improved friction drive forthe gear of thecloth-roll.

Our invention consists in ce 'tain novel loom sufficient to illustrateour: improvements applied thereto.

Referring .te'the drawings Figure 1 is a rear view of a take-u mechanismwith our improv znentsa'pplie thereto, looking in the .tion of arrow 1),same figure.

direction of arrow a, Fig. 2. Fig. 2 is a sec: tion, on line 2, 2, Fig.1, looking in the .d-irec- Fig. 3 shows some of the parts shown in Fig.2, detached, and in an opposite position; the loom frame is broken awayinthis figure, and, Fig. 4 is a section, on line 4, 4, Fig.3, looking inthe direction of arrow '0, same figure, showing the-friction drive forthe cloth-roll.

In the accompanying drawings, 1 is a detached portion of a loom frameend or side,' 2 is the breastbeam, 3 the take-u roll fast on the shaft 4mounted in suitable iearings 5 on the upright frame 6, secured at itsupper end to tie breast-beam 2, and at its lower end to a transverse baron the loom, not shown.

7 is a gear fast'on the take-up roll shaft 4,

v which shaft is operated through a gear not shown on the other endthereof, by a train of gears, and a pawland ratchet, operated from somemoving part of the loom in the usual way. On the shaft 4 of the take-uproll 3, in this instance between the hub of the gear '7 and the bearing5 of the shaft 4, is in this instance looselymounted the hub 8 of an arm8, having an elongated slot 01' opening Specification of Letters Patent.'2 Application filed May 11,1906.

. S." theretlirough, to receive a stud 9 on which is loosely mounted agear 10. By meansof the elongated opening 8" in the arm'8, the stud 9may be raised or lowered therein, to adjust the p'ositionof the gear 10,and then secured in an adjusted position by means of anut 9,see Fig.1.

The swingingarm .8 has aside extension 8 thereon, and extending downfrom, and in this instance integral therewith, is an has secured'thereto a stud- '11, which is adjustable in an elongated'opening intheextension 8, and is secured in an adjusted,' position by the nut 11',see Fig. 1.

The stud 11 has loosely-mounted thereon V the hub 12 'of,a latch 12. Thelatch 12 has an engaging end or rejection 12"- to operate said latch,and said atch has in this instance an opening 12' therein, with tworecesses 12'? leading out therefrom, to receive a stationary stud or pin13 secured to the stand 6. a On the swinging arm 8 is an adjusting crewor bolt 14, turning in a lug 8 on said m, and adapted to engage with itsinner 'end the outer-edge of the" stand 6, as shown in Fig. 2, to'li nitthe inward movement of the swinging arm 8.

Extending in the same vertical plane as the gears 7 and 10, is a thirdgear 15,' in this instanceloosely mounted on an extended end i p Thegear of the shaft16 of the cloth-roll 1 7. 15 is in this instanceyieldingly attached to the shaft 16 in a rotary direction, by a disk 18splined on the shaft 16, see Fig. 4, and a four spring 19 having its hub19 also splined on the shaft 16, and bearing against a bearing 20 forthe shaft 16, see Fig. 1. The spring 19'fore'es the disk 18 against afriction surface 15 on the gear 15, and the revolution of the gear 15,through its frictional engagement with the disk 18, rotates the shaft 16and the cloth-roll 17.

of a nut 21 turning on the, threaded end of the shaft 16. The nut 21bears'against a collar 22, loosely splined on the shaft 16,

and'intermediate then'nt '21 and the hub of 105,

the gear 15. A pin 23, actuated by a spring 24 which extends within arecess within the nut 21, has a tapering end which extends within acorrespondingl shaped recess in the collar 22, and acts to ho d the nut21 in 110 65 'operating handle 8 The side extension 8 position afteradjustment, and prevents it from becoming loose onthe threaded end ofthe shaft 16. There will be'a series of recesses 22inthe collar 22 toreceh e the pin 23.

By mean'sof the swinging arm 8 carrying the gear 10, the gear 10 may bmoved into mesh with the 'gear as shown in Fig. 2, to

drive said gear, through the rotation of the gear 7 and the gear 10, andis held in mesh by the latch 12 engaging with the pin 131, as shown inFig. 2. By means of said swinging arm 8, the gear 10 may be moved out ofmesh with the gear 15, the engaging end 12 of the latch 12 beingdepressed to raise the inner end of the latch and disengage the outerrecess 12 from the stud l3, and allow the inner recess 12? to engagewith said stud 13, as shown in Fig. 3, and hold said gear 19 out ofengagement with the gear 15, so that the cloth-roll 17, through thehandle 17 thereon, see Fig. 1, may be turned fr aly in either di-',rection.

, The advantages of our improvements will be readily appreciated bythose skilled in the art. They are of simple construction and operation,and may be readily applied to loom take-up mechanismsof ordinaryconstruction. By means of our improvements the cloth-roll can be readilydisconnected from, and connected with its operating gears. It will beunderstood that the details of construction of our. improvements may bevaried if desired. 4

Having thus described our invention, what we claim as new and desire tosecure by Let I ters Patent is -1, Ina take-up mechanism of a loom, thecombination with the cloth roll shaft, of a friction clutch member.attached thereto, to

move lbngitudinall y thereon and rotate therewith, a spring for movingsaid clutch member in the direction of the length of the shaft, a

second clutch member loose on saidshaft and in engagement with the otherclutch member,

one of said clutchmembers being a'drivengear, and means for regulatingthe frictional engagement-between said clutch members,

said means com rising a nut turning on the threaded end 0 said shaft,and carrying a spring actuated. pin extending in a p1ane parallel tosaid shaft, and the engaging end of,

said' pin adapted to enter in a collar loosely frictional engagementbetween said cutch members, said means comprising a nut turning onthethreaded end of said shaft, and carrying a spring actuated pin extendingin a plane parallel to said shaft, the en aging end of'said pin adaptedto enter in a collar loosely splined on said shaft, and said collar,intermediate said nut and the hub of one clutch member, said nut andcollar located on the opposite. side of the clutch members from theactuating spring.

3. In a take-up mechanism of a loom, the combination with a driving gearon the takeup roll shaft, and a driven gear on the clothroll shaft, ofan intermediate gear, and a swinging arm for supporting saidintermediate gear, said arm adapted to be moved to carry saidintermediate gear out of mesh with one'of the other gears, or into meshwith one of said gears, and means for moving said arm and means forlocking it inposition, said locking means comprising a pivoted latch tohe moved by the operator and engage a stationary pin or stud.
